RBP4 and Hypertension: Further adjusting for retinol (HR, 1.07 [0.96–1.18]), hypertension state (HR, 1.10 [0.98–1.23]), liver (HR, 1.03 [0.93–1.15]), or kidney function markers (HR, 1.08 [0.97–1.20]) did not alter the RBP4-T2D risk association in men substantially, and none of the tested interactions were statistically significant.
